The Night of Conception
That night, Echidna headed to Roen's bedroom as she always did. Tonight's topic of conversation was the grilled eel.
"I swear, Roen, I don't know how you're so good at cooking. Even tonight, that grilled eel was absolutely delicious. How did you manage to grill a slippery fish like that so perfectly when it's so hard to clean?"
"Back when I was in the adventurer's guild, I was always on kitchen duty. Kitchen duty! The girls would always act cute because they didn't want to get their hands wet, and I ended up doing all the work for them."
"Oh, how gallant."
"I suppose I have a bit of a chivalrous streak."
They say three women together can shatter plates with their chatter, but it wasn't as if two couldn't do the same. The two of them giggled and chatted away. Though Echidna transformed into a monstrous sleep-rapist by night, during moments like this, she became a shy country girl who deeply cherished the time spent with her one and only friend.
"Ah, but thinking about it again, it really was delicious. You said eel is a stamina food, right?"
"Yes, most likely."
"I think it definitely is. My heart is pounding right now, and I can feel this heat spreading through my body. Do you want to listen to my heartbeat?"
"Shall I?"
"U-Uh, sure..."
In moments like this, Roen held the reins completely. Whenever Echidna unconsciously dropped a flirtatious line, Roen would deftly play along, using it as an excuse to initiate physical contact.
"Oh, wow. It's going thump, thump, thump. It's getting faster, isn't it?"
"I-Is it? It must be the eel... It must be incredibly potent."
Roen buried the side of her face in Echidna's chest, smiling up at her with playful eyes, while Echidna bit her tongue to suppress the overwhelming urge to pin Roen down and ravish her right then and there. But there was a limit to how long she could hold back. After all, she was a beast who had surrendered to her lust countless times before.
"Roen..."
"Yes, Echidna-nim?"
"We should probably get started on your final treatment."
She wanted to put Roen to sleep first before doing anything else. She poked Roen's feet, which were hidden under the blanket, with her tail and met her gaze. Roen's burn scars on her feet hadn't fully healed yet. Under the guise of this "final treatment," Echidna wanted to quickly inject her with the sedative and put her under.
"Mmm, well, I'd love to talk with you more... but I know you have your personal research to do, Echidna-nim. It can't be helped. I'll leave it to you again today."
Click, click. Roen unbuttoned her black shirt, exposing her voluptuous breasts. This was her own way of teasing. It was a display of confidence, as if to say, I'm going this far—there's no way you won't be turned on by me.
"Right. I'll see you tomorrow, Roen."
"Yes, goodni—"
Cradled in Echidna's arms, Roen was injected with the burn treatment and immediately fell fast asleep. Feeling the warmth of the sleeping woman in her embrace, Echidna...
"Haaah..."
...let out a heavy, bone-deep sigh. She hugged Roen so tightly it felt as if she might crush her, and whispered into her ear.
"You seductive little thing."
She was aroused. Just as Roen had intended, Echidna was completely turned on. However, there was one thing Roen had failed to calculate...
"Where should I paint you first, hm? Is it really okay for you to tease me like this, Roen?"
When Echidna got aroused, she didn't just produce lubrication; she leaked pre-cum. Well, she did produce lubrication too, but she leaked ten times that amount in pre-cum, and her eventual ejaculation would be ten times the volume of that pre-cum. Roen had truly dug her own grave.
"Shall we start with those magnificent breasts of yours?"
Wrapping her tail around Roen's waist to adjust the angle as usual, Echidna slotted her thick penis between Roen's heavy breasts and began to thrust her hips in earnest.
"My cum is going to be extra thick tonight, Roen."
To say it was stimulating would be an understatement. Every single moment spent with Roen was an ecstasy of pure sensation for Echidna.
"That salted grilled eel you made me really is an incredible stamina food. Maybe not immediately tonight, but by tomorrow and the day after, my load size is definitely going to increase."
Echidna gazed lovingly down at Roen, who was sleeping peacefully beneath her.
"You should be happy. I'll make sure to return every drop of the extra cum you helped me produce right back to you. It's the law of equivalent exchange—a very important theory for alchemists like us."
Panting heavily, Echidna uncoiled her tail from Roen's waist and used the tip to pry Roen's mouth open, keeping it held wide. And then...
Spurt. Splurt. She filled Roen's mouth with thick, snow-white semen, a deep sense of superiority washing over her.
"Ah..."
I was supposed to kiss her too... Echidna thought with a twinge of regret, but it didn't matter. The night was still young.
"What's this? Since when do you wear pants to bed?"
Echidna smirked as she slid Roen's pants down. The last time she had seen Roen wearing pants was probably when they went to the market in the Desert City. She had thought so back then too, but Roen's body type definitely suited pants better than skirts.
"Who were you planning to show off to? Hehe..."
Her plump, shapely rear gave her a gorgeous hip line, and her wide pelvis made pants fit her beautifully. Combined with her thick, bursting thighs, she had the classic build of a female bodyguard. But...
"Up we go."
This stunning woman with the build of a bodyguard was currently lying fast asleep on the bed in Echidna's villa, having her pants stripped off. No, it didn't stop at her pants. In an instant, Echidna pulled off her panties as well. She parted the pale, fleshy slit with her tongue, sliding it deep beneath the clitoral hood.
"Hah...?"
The reaction was instantaneous. Even though Echidna hadn't applied any stabilizer yet, the moment Roen's hips registered the intrusion of the tongue, her back arched like a bow.
"Hngh..."
The semen remaining in Roen's mouth spilled out messily as she let out a pathetic groan. Meanwhile, Echidna slipped a hand under Roen's buttocks to adjust the angle, burying her face in her vulva and working her tongue.
"Ah, hnnh..."
As the sweet, ear-pleasing whimpers repeated without pause, a question mark popped up over Echidna's head.
"What's this...? I haven't even used the stabilizer yet..."
Something was definitely different.
"Mnnnh... Haaah..."
Roen's face, with white semen drooling from the corner of her lips like spit, was visibly flushed. She couldn't keep her legs still, draping them over Echidna's shoulders while her toes curled and her body trembled.
This meant...
"Is she finally fully healed...?"
It was clear that Roen's clitoris was finally ready to emerge. Her clitoris had finally begun to function as a proper organ of pleasure.
"Let's see..."
However, she wasn't entirely sure yet, so she needed to test it.
"Hyaah..."
"Definitely."
The moment Echidna swirled her tongue around Roen's erect clitoris, which was peeking out from its hood, Roen thrashed as if a vibrator had been pressed against her.
"You've really become a complete female now, Roen."
She was highly satisfied. Roen's clitoris had been completely untouched, but through Echidna's consistent application of the stabilizer and careful conditioning, it had been transformed into a perfect organ of pleasure. She loved the feeling that a part of Roen was now entirely under her control.
"Haaah, fuuu..."
Lapping up the sweet love juice leaking from Roen's soaking wet vagina, Echidna began to stroke her own penis with one hand. She had promised herself that she would only claim Roen's virginity after they were married. To keep that promise, she warmed up her shaft elsewhere today as well, using her own hand to prep it.
"Phew... It's about time..."
However, if there was one thing that never changed...
"Let's get you pregnant, Roen. We have to cure your period, don't we?"
...it was that once Echidna started pleasuring Roen's vagina, the subsequent ejaculation would always be inside her. It was only natural; Echidna was the type of person who wouldn't even kiss Roen if she had already ejaculated in her mouth. There was no way she would waste the chance to taste Roen's virgin pussy, which she would eventually penetrate one day. Tasting her before creampieing her was her set routine.
"Hngh, haah... You feel it too, don't you, Roen?"
"Mnnnh... Ahh..."
"This is going to put my seed inside you. It's your period vaccine."
Rubbing her engorged glans back and forth against the entrance of Roen's vagina, she pushed her arousal level to the absolute limit. And finally...
Spurt. Splurt.
"Haaah..."
"Nnn..."
Echidna's thick, sticky semen filled Roen's womb. It was an internal ejaculation just like any other night, and her womb was filled to the brim with cum. But tonight was different from all the nights before.
"They say sperm can survive inside the womb for up to five days, Roen."
Because there was one highly critical difference tonight.
"And your ovulation window is probably in four days. Even with a one-day margin of error, it's five days at most. Do you know what that means?"
Four days until Roen's egg would be fertilized. It was the countdown to the fulfillment of her wish to put an end to her periods.
